Application filed April 29, 1907. Serial No. 370,742.

To al? 1.17.71 om it may concern Be it known that I, HERMANN REICHE, acitizen of the United States, and a resident pf Bellemead, Somersetcounty, New Jersey, have invented certain new and useful Imnovenients inInternal-Combustion Engines, of which the following is a specification.

My invention relates to internal combustion engines, and has for itsobject to provide an etlicient construction by which simplicity, readyadjustment of speed and reliable operation are secured.

A' he features of my invention are chieiy, a novel arrangement'andoperation of two pistons, viz: a power piston and an auxiliary piston,to insure a thorough clearing or scavenging of the cylinder and alsoother advantages; an arrangement by which the i power piston exerts adriving action during both strokes; a novel ignition device and meansfor timing 1t; and' a special mechanism for roi-ating a .shaft by themotion ofv the, power piston and controlling the auxiliary lpiston bythe rotation of said shaft.

' Other features of the invention will be description followingvhereinafter and particularly pointed out in the appended claims.

Reference is to be had tothe accompanying drawings, in which- Figure 1is a side elevation of an engine embodying my invention; Fig. 2 is anelefrom the opposite side; Fig. 3 is a front elevation lwith partsbroken away and parts in section; Fig. 4 is a rear `elevation with4parts broken away and parts in section; Fig. 5 -is a front elevationwith parts removed to show two ofthe central disks, the cylinder' andsome adjacent parts and the shaft beinv shown in section; Fig. 6

The engine shown in the drawing coni- Drises a Acylinder 20 located ontop of a -as shown' in Fig. 5,

casing having a cylindrical wall21 and end wall or heads 22 in which theshaft 23 is journaled. 0n this shaft is secured rigidly a central disk24 provided with an undulatlng guide or groove in its opposite faces,which guide is engaged by pins or rollers 25 projected from theforkedlower end 26n (see Fig. 6) of a rod 26 attached to the powerpiston 27 and passing through stuffing '65 boxes '20a at the bottom ofthe cylinder'. 20. The piston rod 2G is forked at its upper end,

for the passage and movement of a central piston rod 28 and a yoke 29which ,are rigidly'connected with the auxiliary piston 30 located in thecylinder`20 above the power piston 27.. The piston 3() is preferablyhollow and in communication with the hollow piston rod 28 open at bothends to the air, said rod extending from both sides of the auxiliarypiston and passing through a stuiiing box 20b in the cylinder head andthrough another stuffing box 27a in the power piston. A delector 30:tmay be located in the auxiliary piston lto compel a spreading of thecurrent of air which rushes through the piston and piston rod duringtheir reciprocation to. cool The pins or rollers 25 also engage `guidesor grooves in two disks 3l mounted loosely on the shaft 23 at each sideof the disk 24, these three disks forming a central set of disks fnti-oiled directly by the power piston 27. The grooves or guides ofthese disks are of the peculiar formation shown in Fig. 5, each guidehaving portions 32 which are arcs of a circle whose center is on theaxis of the shaft 23, and converging, outwardly extending portions 32,32"., the. outer ends ofwhieh are connected by rounded portions; Theguides therefore have a somewhat star-shaped ontline. The guides of thetwo disks 3l are al ways similarly located, that is, correspondingportions of them register lengthwise of the shaft, but the guide of the'central disk 2l is sometimes staggered with reference to those of thedisks 31, that is, 'the pointsV of the guide on the central disk comebetween the points on the disks 31 in positions such as the one shown inF ig 5. it will be obvious that a reciprocation of the power piston 2?will cause the .disk 2li to rotate in one direction, and the disks 31 inthe opposite direction. .ik positive connection is effected between thedisks, by providing them with so as to leave a clearance them andindirectly the pinions 33, which are mounted on stationary tions.

V l pel the onstationary .respond to the pinions 33 in function andstuds 34. Each pinion engages teeth on the disk 24 and on one of thedisks 31. For the Sake of cleariiess'only one such pinion has p F ig. 5,but generally I will been shown in employ, two in diametrically oppositeposi- Such a pinion or set of pinions is provided on each face or side.of the central disk 24. The piston 27 drives'the` rotary `members ordisks 24 and 31 as long as the y pins or rollers 25 engage the guideportions 32?, 32b (both strokes of the power piston being activestrokes, as hereinafter described) the momentum of the engine parts 1srelied upon to rotate the'disks 24, 31 while the pins 'or rollers 25engage the guide portions 32.

The yoke 29 (connected with the auxiliary piston 30) has arms 29adepending between lateral sets of rotary members or disks provided'withfully described hereinafter, which guides p are vengaged by pins orrollers '36 similar tol All the lateral disks the pins or rollers 25. 35are loose upon the shaft23, and to comtwo disks 35 of the same set torotate in `opposite directions, I providethem with gear teeth 35a,Vwhich mesh with pinions 36 (one of which is shown in Fig. 7) mountedstuds37. These pinions cor* arrangement. To the outermost disk -35 of ytogether each set is secured rigidly a gear wheel 38 in mesh with a gearwheel39 held to rotate with a smaller gearwheel 40, as by keying both ofthese wheels on the same journaled in the casing.V Each gearwheel40meshes with a gear wheel 42 keyedjto the shaft 23. In theparticular` case "illustrated, the wheels 38, 39 are .of equaldiameters, and thewheels 42 twice as large that the lateral disks 35fast as the central disks as the wheels 40, so will rotate twice as24,31. vPower may i 23 or 41 by means of any well-known or apf l 1 Figs.4 and 7) comprise outerportions 43' 50 proved devices.

at the ends fof each are the -shaft 23 (two revolutions of the disks 35)the ower piston 27 will have eight strokes (four inwardand four outward)and four periods of rest while 'the auxiliary piston 30 will havesixteen main strokes (eight inward and eight outward), and four vperiods of comparative rest. The exact succurs'during what I have termedthe period of comparative rest, while the pins or rollers 36 travel inone-of the arcs 43. For this purpose, the disks 35 are provided at thearcs 43, with slides 44, having inward projections 44a,whic h obviouslywill give th.- pins 36, and therefore the auxiliary pistoll` 30, a shortinward movement.

In order that the timing ,ofthe ignition may be varied, the slides 44.are adjustable circumferentially along guides 35h. and are providedwith segmental racks 44b engaged by 'pinions 45. Each pinion is rigidlysecured to a radial shaft 46' journaled in abearing 35c on the disk 35,and also journaled in a slide 7 movable on radial slideways 48 securedto the disk. The shaft 46 has a spiral groove 46*L and the slide 47 aThe slide 47 further carries an outwardly projecting pin 47a'wliich (asthe disk 35 rotates) is. adapted to vpass between the oppositelyconvexed arms 49 secured toan actuating'lever 50 fulcrunied on thecasing at 50a. There are two such levers, as shown in Fig. 2, providedwith forked ends 50? (Fig. 4') into which project pins at the ends of anadjusting frame 51 provided with a handlev 51a and adjustable verticallyin g1 1ides'51D on the casing, and locked by As long as the levers 50areinthe same position, the slides- 44 Willremainin the same position. Ifhowever the levers 50 .are raised or lowered, the arms 49 will strikethe pins 471 and move the slides 47 in or`o`ut, causinga proportionalrotation ofthe radial shafts 46 and circumferential` shifting of theslides 44- in one direction or the other, andconse- Eguentlyan advancingorfretarding of the` ignition stroke.l

lThe auxiliary piston is provided with passagesA leading through it andcontrolled by inwardly-open in g Avalves 53 which open automaticallyduring the outward (upward) stroke' of said piston-to let .of air,l orof combustible mixture pass :from Aabove toffbelow the auxiliarypiston.. This a charge either charge enters,throughaninlet at thetop liin.,

awhirling motion to the air'entering the spraying chamber 58a. Air issupplied to said inlets from two compressors 62, provided at each endwith ports 62?1 having connections 63 leading to the corresponding iii.-let pipe 61 and controlled by check-valves (ill'opening toward the Eachcompressor cylinder contains a chambered piston 65 havingtop and bottomopenings controlled by double valves 6G arrange do be operatedautomatically when the piston reverses its'motion. Each 'valve comprisestwo heads adapted to become seated on seats in the respective end facesof the piston 65, vand a stem connecting said heads and of such a lengththat only one of the heads can be seated at a time. lVith the piston iscon- 40 neeted a hollow piston rod 67, open to the chamber within thepiston, by a slot 67, to the inside of the casing, from which it drawsthe supply of air, it being understood that air has free access to theinterior of the casing through the hollow piston rod 28. The piston rods67 are secured to the yoke 29, as by screwing. During the upward strokeof the yoke, the upper valve heads are seated, air is drawn into thechamber below the piston 65 through thehollow piston rod 67, since thechamber within the piston is open to the chamber below the pist0n; atthev same time air is expelled' from the chamber above the piston andforced over to the carl'iureter. "When the piston travels downward, thelower heads vof the Valves 66 become seated, causing the interior of thepiston 65. to communicate with `the chamber'abore the piston, into whichchauibei' air is drawn through the hollow pistonfrod, while at the sametime air is forced over to the carbureter from the chamber bei low thepiston.

and also open, as

.more copious iiow of a serrated edge aid in thoroughly mixing thegvasoleue or other fuel with the air. y -Below the partition 58 islocated the fuel chamber or liquid chamber 58d, to which gasolene may befed at the start through a priming connection 68. 4"Vlfhen the engine isrunning, the fuel is supplied through the gasolene pipe 69 in which islocated a valve 70 seated by the pressure of the liquid and also by aspring 70El (see Fig. 8). The angular stein of the valve 70 is projectedinto the carbureter and carries a convex roller 7l mounted to turn abouta vertical axis and arranged for engagement with the convex surface ofthe rim 72 which forms part of a fan wheel. The rim 72 has a spider 72aconnecting it with a hub 72b iittedto slide and turn on a sleeve 58Cprojected upwardly from the bot- To the lower pointed ends of fan bladeswhich are inclined upward and inward, each blade having a centraldepression 'or ridge 73b toward which converge thetwo opposite inclinedsurfaces 73 and 73a. The blades are fastened at their upper ends to asmall ring 7 4, and may be connected at their lower poi'- 'I he partsshown in Fig. 10 are rigidly connected and form the fan wheel. Two armsof the spider 72a are provided with openings 72c through d. which extendloosely vertical arms 76a secured to a crown 76b forming part of thefeeder shaft 76, contained in the sleeve 582. By this construction thefan wheel is com- .pelled to rotate with the feeder shaft, while free tomove lengthwise thereof. lt will be understood that'wh'en the fan wheelrotates, the gasolene struck by the inclined blades will cause the wheelto rise more or less on the shaft, according to the level of theVliquid. The i'iiii 72 will press on the roller 71 and open the lvalve 70 more or less. The rise of the fan wheel (which will tal-:e placewhether it rotates in one direction or the other) will up to a certainpoint cause a gasolene, but an excessive rise will throttle the passageor even bring the rim 72 entirely above the roller 7l, causing the valve70 to close fully. A collar 77 serves to secure the shaft 76 againstlengthwise movement. The crown 7 6b has (see Fig. 11) so as to drive theliquid away from the joiiit between said crown and the sleeve 58e.

To the upper end of the shaft 76 is secured the downwardly taperingfeeder 78 which is fitted into a corresponding socket 79 located at thecenter of the partition 58". The feeder has one or more spiral grooves78u on its conical surface, thc upper ends of such grooves communicatingwith the mixing or spraying chamber 58, while their lower end or endswill register at times with grooves 7 9a on the inner surface of thesocket l 79. Then there are two grooves 7 8a,

preferably extend in opposite directions as they y below is whirledupward and outward by ter with the grooves 7 9a centrifugal force anddischarged into` the spraying chamber 58 where it becomes mixed withair. The faster the feeder rotates, the oftener will the grooves 78aregisduring the same period of time, and the greater the amount ofgasolene or other fuel fed to the mixing or spraying chamber.

The mechanism for rotating the feeder 7 9 is shown best in Figs. 3 and6. On the lower end of the feeder shaft 76 is 1 ounted a friction disk80 held to turn withl the shaft but capable of sliding thereon togetherwith a forked carrier-81 movable upland down 011 one ofthe heads 22 andrigidly connected with a rack 82. Guides 22El are provided for I therack 82 anda guide .slot22`D for-the passage of the carrier 81. The rackis in mesh with a pinion 83, wide enough to also engage a toothed sector84s which, like the pinion, is journaled in the end plate or head 22. Aweight 811@ tends to keep the sector inthe central position shown inFig. 3, and the friction disk 80 at a corresponding normal level. If theengine is used, say on an automobile, and so disposed that the sector8.4

will swing in a plane lengthwise of the carv riage (that is, having theshaft 23 disposed transversely of the carriage), then as the automobilegoes up hill or downhill, the pendulum sector 84- will automaticallychange fthe position of the friction disk 80 relatively to center thefriction disk 85 by which it is driven. The speed of the feeder shaftl76v will thus be increased or diminished automatically as the carriagetravels up hill and l downhill. Alhen the engine is stationary, I 5 .theautomatic governorj ust described is dispensed with, the friction disk8.0 being secured rigidly to the shaft 76 in this case.

The friction disk 85which is journaled in Y downward, thus reducing thevspeed of the. vfrictionfdisks 85, 80 and that of the feeder 78, andcorrecting the engine speed. In the e reverse case, the governor ydisk,will. move j k65'. "1.15. is turn'edvto connect thezport 111 tempoastationary bracket 86, is driven by a frictiondisk 87 mounted to slideon a shaft 88 and controlled by a governor 89. The governor shaft 88 isjournaled in stationary brackets 90 and carries a friction wheel 91engaging one of the lateral disks 35 .and driven thereby. 1f the enginespeed increases, the governor disk 87 will vmove upward,"increasingtherotary speed of" the means,vsuch as a feeder.. A n' automatic speedregulation is to the mixing chamber 58a. v Insome cases it may bedesirable to' alter the normal speed to which the engine will be heldbythe operation of the governor v89. For this purpose the friction wheel91, while alwaysrotating with the' governor shaft 88, may be capablev ofsliding thereon, being connected with a slide 92 adjustable up and downadjacent to a slot 220, by means of a lever 93 fulcrumed at 93a and heldin po-sition after adjustment, by any suitable' pawl engaginga segmentalrack 94.v n

In the bottom of the cylinder 20 is arranged an exhaust port controlledby a valve (not shown). This valve isl operated Ine,-

chanically at the proper time by a lever 97 fulcrumed at 98 on a bracket99 and loosely connected with a rod 100 sliding in stationary parts,such as the brackets 90. The inner end of this rod carries a roller 101arranged to be engaged by the inner surfaces of two'cams 102 on one ofthe disks 35, it being remembered that this disk rotates at twice thespeed of the shaft'23, so that the exhaust valve 95 will beA operatedfour-times for each revolution of said shaft.

At the bottom of the cylinder 20 is further arranged an inlet portcontrolled by an automatic inwardly opening valve 103 and connected by apipe 104 (EigsQ- 3, 5 and Y 6) -with a chamber 105. This chamber lhasanother connection 106, controlled by an inwardly-opening valve'107 andleading to a pressure tank' 108 and toa` storage tank 1081. Thechamber-105 has a third connection v105" llows: one, designated. as 110,leading toa PL relirninary exhaust port 111 located in theside of thecylinder 20 at a level slightly above the top, of the power piston' 27when the latter is at the end of its downward stroke; a secondconnection 112 leading to the tank 108 and provided with a check valve113 opening toward said tank; and a third c^nnection 114, leading to theair. A rotaryplugll is mounted in the valve casing 109 and is normallykept in the position shown in Fig. 5, by means of a spring 116 acting ona vertically sliding ed 117 which is providedv with a rack 117%-in meshwith a pinion 115 on the plug 115 .(seeliig. 4)'. Thus, norles Inallythe preliminary exhaust port 111 is in communication, through theconnection 110,-valvecasing 109, passage of the plug 115, connection1051 and chamber-.105, with the pipe 101-\leading to' the inlet'valve103 v:ai-the bottonrl'of the cylinder 20,v

At times specified hereinafter, the Vplug working stroke, the auxiliarypiston at end of the rod 117 is connected, by a link` 11S, with a lever119 fulcrumed on the second end plate 2E? at 119a and provided with aroller 119b to engage two cams 120 on the adjacent end disk 35, so thatthe valve 115 will be operated four times during each revolution of theshaft 23, since said disk rotates twice as fast as the shaft.

I' prefer to make one end of the cam 120 with a gradual incline, and theother with an abrupt shoulder, so that the valve 115 \may open(comparatively)y slowly, and close suddenly, for purposes hereinafterstated. `ihen the engine is tov be reversible, I employ two sets of cams120, 120, located similarly, and differing only by the fact that thegradual incline is at that end of a cam 120 where the corresponding cam120, has an abrupt shoulder, and vice versa. The cams 120 are in oneplane, and the cams 120a in a diii'erent plane. In order that in thiscase the roller 110b may be made to register automatically with theproper set of cams, according to the direction of rotation, I providethe following construction: The roller is provided, at its centralopening, witha pin 110c projecting into a groove of the stud 110| onwhich said roller is journaled, the stud being rigid with the lever 119(see Fig. 14'). The -said groove comprises a helical portion 119e`connected at each end with a transverse annular portion 119 Springs 121secured at the ends of the stud tend to shift the roller 110b lengthwiseof the stud, giving the roller pin 110 a tendency to enter the helicalgroove 119e. These springs engage the roller loosely.

The operation of 'the pistons in the cylinder E20 is as follows, itbeing- 'understod t iat the' movements of these pistons are governed bythe guides of the rotary members or disks 9,4, 231 and 35. Let usassumethe power piston Q7 has just completed its `downward thattime bein'gatthe top ofv the cylinder. The preliminary exhaust port 111 beingunecovered, and the valve 115 standing in the osition shown in Figzv, theexhaust passes through the pipes 110', 105 and 10-1to the chamber belowthe power piston. 27, the valve 103 opening automatically, while thevalve [107 is kept closed by 'the pressure. Then, while ther powerpiston remains stationary, the auxiliary piston performs three strokesas follows. First, a downward stroke, at the beginning of which thevalve l115 is turned, by the action of one ofthe cams 19.0 or 120210place the preliminary exhaust port 111 in communication for a short timewith Vthe tank 108, which thus receives a portion of the combustionproducts, and immediately thereafter the port 111 communicates with theair through the port vthe cubic contents ofthe cylinder.

or connection 114i, with which it remains in communication during thenext three strokes of the auxiliary piston. The valves 53 closeautomatically during the downward stroke of the auxiliary piston, andduring the first downward stroke the rotary valve stands in such aposition that the upper end of the cylinder, above the auxiliary piston,communicates with the outer air, so that said end becomes filled withair as the piston descends. Second, the auxiliary piston moves upward,causing the valves 52E to open and air to pass from above the piston tobelow it. Third, the auxiliary piston -moves down again, the valve 55,now standing in such a position that the lupper-end of the cylindercommunicates with the 'carlmreter, so that a charge of the combustiblemixture ready compressed to a certain extent by the action of the aircompressors), is admitted to the upper'end of the cylinder, the volumeat'atmospheric pressure being greater than At the same time, the aircontained in the chamber between the two pistons 27 and 30, is expelledthrough the outlet 114, together' with any remnant of burnt gases, thusscavenging the working chamber, and also cooling it and the pistons. Thecooling is also assisted by the passage of air through the auxiliarypiston and its piston rod, as said piston reciprocates.

Just before the auxiliary piston reaches the end of its second downwardstroke, the valve A115 still connecting the port 111 with the outsideair, the main piston starts on its upward stroke, the pistons meeting atabout the level 'of the port 111 so as to entirely expel the air. Thenboth pistons move upward, the auxiliary piston, however, moving fasterso that'it reaches its upper position, atthe top of the cylinder, beforethe Ipower piston has completed its stroke. As soon. as the power pistonrises, port'111. The upward movement of the plpwer piston isassisted bythe pressure of t e mitted to the lower end of thecylinder, and also bythe iow of gases from. the tank 108, the valve 107 opening towardl thepipe 104 and closing the lower end ofthe connection 1051. At the sametime, the valves 53 close and the combustible charge 1s compressedbetween the two pistons 27 and 30. As the power piston approaches itsupper position, its lower end uncovers the port 111 and some of thegases escape from below the piston to the air through the outletv 114.Then the valve 115 resumes its normal position shown in Fig, 5 (thelroller 119? coming off the cam 120 or 1201) and the auxiliary piston isgiven' the short ignition stroke hereinbefore referred to, whereby thecharge is subjected to a sudden increase of pressure, suilicient to,

ignite' it'4 throughout vthe working chamber,

it closes the gases which have been previously adi-.v

Y and not only locally, as is the case with elecactionl of one of thecams 102, and the re-- sistance to the downward movement of the tricignition. The power piston then has its downward working stroke, theauxiliary piston remaining at the top of the cylinder. At a suitablemoment during this stroke, the exhaust valve' 95 is opened through thepiston is removed. This exhaust valve closes at the proper timecolinciding more or'l less with the end of the pistons power stroke.iachdownward stroke of the piston is a combustion lstrokeor powerstroke, and some power is alsoexerted during each upward strol 1 Thecompressed gases stored in the tankl 108 may vbe used to start theengine, by admitting them through a pipe controlled by a manuallyoperated cock or valve, either below or above the power piston.

The sudden and complete detonation of the charge' which results fromtheparticular method of-igiiition employed by me, in sures a material'increase in power. With my invention, there is no danger ofafterburning, the exhaust is cooler, a greater oompression 'isavailable, and the power `is also y increased by reason oi' the lgreatervolume of the explosive mixture forced into the cyl, inder.
